I saw the stuff about an updated Android API in the comparison to BT LE page http://www.thisisant.com/developer/ant-plus/ant-ble-comparison/
Good stuff although the fact that there is no support for BT LE in Android from Google yet is a rather big drawback.
I am interested to know if there is any timeframe for the updated API framework becoming a reality. Having written my aplications in a way similar to this because I saw the need myself I am quite keen to go to a proper multi app solution as soon as possible. On a practicle front my the next feature I am planning to add is footpod support and tempreture support so if the release was going to be soon I would look to delay the work to pick up hopefully easier coding solution.
